Clear Open Items

Experts,

I am planning to clear some vendor open items through LSMW - Before doing that, i wanted to do a normal manual g/l entry - I created a new document type for this kind of transaction, but that how would the g/l entry i enter close the open item of the vendor because the G/L entry i am doing is simply going to Dr the vendor account and Cr the clearing account ( i created for this purpose) .

Would that be enough??

All answers would be duly rewarded with points.

Thanks,

Nandita
